A recent Shipyard change [0] introduced user-context tracing support in
Shipyard, which requires the passing of an additional parameter to the
Deckhand and Drydock API clients. The Deckhand [1] and Drydock [2]
clients were updated to handle the additional parameter, but the
versions of those components used by Shipyard was not updated. This
change uplifts the versions of Deckhand and Drydock in requirements.txt
for the Airflow component of Shipyard to a version that supports the
aforementioned, additional, user-context parameter.
